REVOLVER.

SPECIFICATION forming part of Letters Patent No. 355,76fdated January 11, 1887.

Application filed October 25, 1886. Serial NoQlLOE'I.

To all whom it may concern:

Be it known that I, SULLlVAN 'FOREHAND,

Vorcester, in the county of Worcester and State of Massachusetts, have invented a newand useful Improvement in Revolving Fire- Arms; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

. My invention relates to that class of revolving fire-arms in which a many-chambered revolving cylinder is used in connection with a single barrel; audit consists in the novel manner of connecting the cylinder with its central stem or spindle, upon which it revolves, as will be hereinafter fully described.

Referring to the drawings, Figure 1 represents a side elevation of a revolving fire-arm with parts broken away to more clearly illustrate my invention applied thereto. The barrel vportion is shown tilted uponjthe stock. Fig.

2 represents a'plan view of the central spindle of the cylinder detached from the revolver; Fig. 3, a side view of the spindle; and Fig. 4, a central vertical section of the spindle, and also of a portion of the cylinder.

In the drawings, A is the stock of a revolver of any ordinary construction. B is the barrel portion; hinged to the stock and adapted to be tilted thereon, as shown.

.0 is the cylinder, supported upon and se cured to the central stem or spindle, D, and adapted to revolve'thereon. The spindle D is made hollow, as shown, adapted to receive the ejector-stem, upon the end of which is secured the cartridge-ejector in the usual manner, the ejector being operated by means of an ejectorlifter secured at the hinge of the revolver in I any usual and well-known manner.

I have not shown in the drawings the ejector and means for operating the same, as they form no part of my presentinvention, and are old and well-known devices usually employed in this class of revolving fire-arms.

The spindle D may be enlarged at one end, and said enlarged end abe adapted to fit tightly into a hole, 1), formed in the barrel portion B of therevolv'er. (See Fig. 1.) A longitudinal (No model.)

groove, 0, is made in the exterior surface of the end a of the spindle .D, which at its inner end may extend through the shell of the spindle, as shown in .Fig. 3. A longitudinal opening or slot. d, may also be made in the end a, (see Fig. 2,) to allow of the lifter-finger moving back and forth therein to operate the ejector-stern and ejector in the usual manner.

A flat spring, E, is fitted into the groove 0, and secured therein in any suitable manner, so that its upper surface will be flush with the exterior surface of the end a of the spindle D. (See Figs. 2 and 3.)

The forward end ofthe spring E projects beyond the portion 'a of the spindle D, and has ahook or catch, e, formed thereon, adaptedto engage with a circular recess, f, formed in the central part, 9, in the forward end of the cylin der, (see Fig. 4,) when the cylinder is in its proper position upon the spindle D. I

A knob or projection, h, is formed upon the upper side of the spring E, and extends up from the same and through an opening in the barrel portion made to receive it, and its upper end projects above the plane surface of the barrel portion. By means of the knob h the catch e is depressed, allowingthe cylinder 0 to be disconnected and removed from the spindle D. The knob 11, projecting through drawn out by a small. pin, 2, secured in the barrel portion and fitting into the vertical groove j, made in the outer surface of the enlarged end a of the spindle D. (See Figs. 2 and 3.)

From the manner of construction of the spindle or stem D above described, in connection with the circular recess f, formed in the central opening of the cylinder 0, it will be read ily seen that the cylinder 0 will be securely held in position and prevented from any longitudinal motion upon its central supporting spindle or stem, D, and at the same time be allowed to revolve freely thereon, and to be disconnected and removed therefrom, when desired, by simply pressing upon the knob h,

' der, which projects beyond the end of the cylinder, (see Fig. 4,) and the spring E be made so that its notched end will extend through the barrel portion B, at either side of the spindle D, and engage the external recess formed on the central part of the cylinder, upon the opposite side from which the knob h extends, without departing from the principle of my invention, which covers, broadly, a tubular central stem or spindle provided with a spring adapted to engage with the cylinder to secure the same to the stem, and at the same time allow of the free rotation ofthe cylinder thereon.

Having thus described my invention, what I claim as new, and desire to secure by Letters' Patent, is

1. In a revolving fire-arm,the combination, with the revolving cylinder provided with a circular recess for the purpose stated, of its hollow supporting-spindle provided with a spring having its end notched and adapted to engage with the recess above mentioned, to allow of the cylinder revolving freely upon said spindle and prevent any longitudinal motion thereon, substantially as set forth.

2. The combination, with therevolving cylinder 0, provided with the circular recess f, for the purpose stated, of the hollow station- ,ary spindle D, and spring E, secured therein and provided with a catch adapted to engage purpose stated.

3. The combination, with the tubular spindle D and spring E, provided with a knob, h, and catch a, of the cylinder 0, provided with a circular recess, f, for the purpose stated, substantially as shown and described.

4-. The combination, with the spindle D, having the groove 0 formed therein, and the spring E, provided with a knob, 72, and a catch, e, secured in said groove,ofthe cylinder 0, having a circular recess, for the purposestated, substantially as shown and described.

5. The combination, with the barrel por- ,tion and the cylinder provided with a circular recess, f, for the purpose stated,of thespindle D, provided with a spring, E, and a pin, i, adapted to engage said spindle and prevent any movement thereof, all constructed substantially as set forth.
